Investors in certain "AAA" resecuritizations won't be happy. Late last night, Moody's downgraded a bunch of securities, even though they are supported by Agency-guaranteed RMBS.
Many of these were downgraded from Aaa to junk (some at Ba1, others all the way to B1) in one fell swoop, while others went only to A1. (It looks like S&P still carries most of these securities at AA+, which is lower than Moody's Aaa as S&P has downgraded the United States to AA+.)
What's most interesting here is the reason. It's not the case that either Fannie or Freddie hasn't paid up on their guarantees, but it looks like the deals may not have been modeled (possibly ever!) - or at least may not have been modeled correctly. According to their press release, the resecuritization vehicles seem not to have the necessary protections in place to support the bonds issued, or the ratings provided. Some of these deals were structured in 2007 and even late 2008. Many of these deals are already suffering shortfalls.

From Moody's press release:
"The downgrade rating actions on the bonds are a result of continual interest shortfalls or lack of adequate structural mechanisms to prevent future interest shortfalls should the deals incur any extraordinary expenses."
... and ...
"Interest due on the resecuritization bonds is not subject to any net weighted average coupon (WAC) cap whereas interest due on some of the underlying bonds backing these deals is subject to a net WAC cap."
... and ...
"Since the coupon on the resecuritization bonds is currently higher than that of the underlying bonds, the resecuritization bonds are experiencing interest shortfalls which on a deal basis are accruing steadily."
Total issuance of $483mm affected, according to Moody's. Deals are of Structured Asset Securities Corp. and Structured Asset Mortgage Investments shelves.
